AM3517 USB OTG same as AM3730/OMAP3530 OTG??

Other Parts Discussed in Thread: AM3517, OMAP3530, AM3703

Is the OTG host controller integerated in the AM3517 the same core IP as that in the OMAP3530/AM3703?

If I have a working OTG software driver that runs on a AM3517 will the same driver work on the OMAP35xx and AM37xx?

Assuming any base register remapping of course.

It is not clear in the OMAP3530/AM37xx TRM if the DMA is the same as that in the AM3517 whos TRM has a lot more interface info.

    Yes, the core IP is the same on both platforms.

    What driver is it? depending which layer your driver sits in, there might be a little porting work from one platform to another.

    The DMA is different. AM3517 uses CPPI41 DMA, OMAP3530/AM37xx uses System DMA. They are all external DMA to the OTG controller IP.

    I have working High Speed USB Host (I am not referring High Speed OTG Host )on AM3517evm and AM/DM37xevm boards

    1. Is High Speed USB OTG (Peripheral/Function Mode) also same on both boards.

    2. There is no Register Manual for USB OTG in DM37xevm Technical Reference Manual. How to get it?

    3. On DM37xevm board, OTG Peripheral mode is using NXP ISP 1507 transceiver. Is it right?

    4. On am3517evm board, we have a register LVL_INTR_CLEAR at 0x48002594 to clear USB Interrupts. It is missing on dm37xevm?
